Association of tumour-associated macrophages with cancer cell EMT, invasion, and metastasis of Kazakh oesophageal squamous cell cancer

Table 4 Cross correlation analyses reveal strong relationships among density of TAM in tumor nest, tumor stroma and expression of E-cadherin and Vimentin in Kazakh ESCCs

Characteristics	TAM density in tumor nest r / P	TAM density in tumor stroma r / P	E-cadherin r / P
TAM density in tumor nest	1
TAM density in tumor stroma	0.380 /<0.001*	1
E-cadherin	0.066/0.517	−0.112/0.272	1
Vimentin	−0.166/0.102	0.319/0.001*	−0.619/< 0.001*

Partial correlation analysis method was employed to calculate the correlation coefficient of the corresponding two variables(eg. TAM in tumor nest and TAM in tumor stroma) with adjusting the other two variables (eg. expression of E-cadherin and expression of Vimentin). *p<0.05
